How to Write a Summary of an Article? How do environmental factors affect the transpiration process in plants? Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.

Transpiration is the process through which water is evaporated from plants. This serves many purposes, including thermoregulation and the diffusion of CO2, but most importantly creates a water potential difference which causes the mass flow of water and nutrients from the roots to the leaves of the plant.

Transpiration is accomplished through structures on the surface of the leaf called stomata, which are guarded by a pair of guard cells. This experiment was conducted to learn more about this process, and how certain common environmental factors affect it.

Plant transpiration increases with the presence of wind due to increased evaporation from leaves. The transpiration rate of the sunflower in the presence of wind was consistently greater than that without wind, also causing the mean to be higher, shown in Table 1.

Also included in Table 1, the variability was less in the sunflower with wind along with standard deviation.

Rate of Transpiration in sunflower plant with and without wind. Although the rate of transpiration was consistently, noticeably greater while wind was present than it was in the absence of wind, there were some limitations to this study.

The main shortcoming is that, because only one plant of one species was used, this cannot be used to generalize that this is true for all plants.

In general, the results support the hypothesis that the rate of transpiration is higher in plants while wind is present. Transpiration increases in the presence of wind for two main reasons. When the stomata open, the wind would increase evaporation and the amount of H2O that escapes from the open pores.

Also, when water is transpired it remains around the plant, causing area within the vicinity to become humid. Wind pushes that saturated air and replaces it with drier air, which is easier for water to evaporate into. Further studies could include not only other variables affecting transpiration, such as relative humidity of the atmosphere, temperature, pH of water and amount of available water, but also how much each of those individual variables contribute to the rate of transpiration in relation to each other.Cacti grow in arid regions such as deserts.

Compared to other plants, b transpiration in cacti would most likely be which of the following? a. Lower b. Higher c. The same Describe the process of transpiration in vascular plants. Evaporation of water through the stomata of the plant through the leaves.

The movement of water through a plant is facilitated by osmosis, root pressure, and the physical and chemical properties of water. Transpiration creates a lower osmotic potential in the leaf, and the TACT mechanism describes the forces that move water and dissolved . April Plants Transpiration Introduction Plants transpiration is a process that can make differ by a plant, depending on the environment.

Transpiration is the evaporation of water from aerial parts of plants, especially from leaves but also from stems and flowers. Transpiration Lab Essay TRANSPIRATION DESIGN LAB Transpiration is the process through which water is lost from a plant.

Water is taken into a plant through roots and root hairs by osmosis, and it exits the plant through stomata.

In the presence of a windy environment, plants will do transpiration more as the removal of water from the. Essay Lab Report: C3 And C4 Plants C3 and C4 plants can be distinguished based up the type of carbon containing molecule they make.

C4 plants get their name because the first carbon containing molecule they make during the process of photosynthesis is a four-carbon compound while C3 plants make a three-carbon compound.

In lab 3b, all of the plants should lose a lot of water through transpiration, but those affected by the light and the fan will lose a larger amount of water. Therefore the hypothesis can be the factors that increase evaporation will increase transpiration.
